I am to preparing to uninstall nusb3.3 and replace it with nusb3.6. However there are a number of things I am unsure/unclear about. 1. From Maximus Decim (various posts) - “*Native (without installation of additional drivers for each type) support USB flash drives, digital photo and video cameras and other similar devices” suggests that nusb33 covers all USB devices yet most other posts seem to refer only to Mass Storage Devices. Some cameras are seen by Windows as MSDs, but not all. From - http://www.msfn.org/board/index.php?app=core&module=search&do=search&fromMainBar=1 – the link to this thread is broken; apparently this quote is from a post by Lone Crusader on May 23 2013 - “Q. What is a "native USB driver," as opposed to any other kind of USB driver? A. Native means, as the name implies, built-in USB driver support without the need for installation of additional drivers for each type of USB device being used.” This does suggest that Nusb supports any USB device. Is this correct? However, from post #888383 by Bizzybody, 17th Oct 2009, in (referring to nusb33e) “This driver DOES NOT SUPPORT non-storage devices such as scanners, printers, tablets, cameras/phones that *don't* have a drive/disk/mass storage mode, or any other device that doesn't act like a disk drive.” Perhaps this has changed with nusb36e. 2. From Maximus Decim - “*Universal Stack USB 2.0 (without installation of additional drivers for each chipsets) with uninstall.” The meaning of this is unclear except to gurus. Presumably this means that Nusb overwrites the existing Universal Stack … with a new one. My understanding is that if Windows cannot find a Universal Stack it writes a new one so presumably if the existing stack is deleted and Nusb installation inserts its own one Windows is happy with that and doesn’t change anything. Is this correct? 3. Further, from the same quote – “with uninstall”. What does uninstall here refer to – does it automatically uninstall an earlier version if present before installing the new one, or does it mean that the new version includes and uninstall procedure for removing itself if required? 4..I have read various postings about the advisability of periodically clearing out USB device entries using Safe Mode Device Manager. I propose to do so before starting the procedure for installing Nusb – is this a good idea, and if so I presume that this process should be fully completed and a restart performed before starting the Nusb installation? Currently I have 22 entries in Safe Mode Device Manager (with no USB storage devices plugged in), with entries under “? Other devices” (2, both with ?), Storage device (8, 7 having the same pair of drivers) and Universal Serial Bus Controllers (12, including 2 for printers which are in use. In the last group are entries for Unknown device, USB root hub and USBPort driver – would one of these be for the 4-port USB hub which is always connected? If not, would this hub have an entry and what would it be? In Normal Mode Device Manager, with no USB storage devices connected, there are only 4 USB-related entries – there “would” be 5 but only one printer is connected at a time). I am not sure how to best to go about this as advisories I have read are inconsistent. From Bizzybody’s post (#731 in ) it would appear that one starts with Add/Remove in Normal Mode. Most methods then say to remove USB device entries found in Normal Mode Device Manager then boot to Safe Mode and remove any others present, then reboot to Normal Mode (? cancelling any Windows requests to reinstall drivers – Bizzybody); ? then recheck in Safe Mode (http://www.usbman.com/Guides/Cleanup Device Manager Safe Mode.htm) (can't make this link include the whole title), then reboot to Normal Mode and install nusb36. The correct order of removal is pretty universal and its importance emphasised, but where do ‘Other devices’ and ‘Storage devices’ other than flash drives come in the removal sequence? I would be grateful for clarification on these points. TIA.
